Provided is a dispersion composition that makes it possible to satisfactorily disperse metal oxide microparticles as well as to achieve both good optical performance and good surface smoothness in a cured product after curing. The dispersion composition pertaining to the invention contains dispersoid particles (A) that are metal oxide microparticles having an average particle size of less than 50 nm, a dispersant (B) comprising a compound shown by formula (1), and a polymerizable compound (C). The dispersant (B) is combined within a range of 3-20% by mass relative to the total solids content. (in formula (1), R is a C3-24 linear alkyl group or linear alkenyl group, AO is a C1-4 oxyalkylene group, n is an average added alkylene oxide mole count of 5-30, X is a linking group comprising a carbon atom, hydrogen atom and/or oxygen atom) |
